Re: [math-fun] Slight change in the rules of chess

this is actually an issue in the chess variant played with two kings (and no queens), in which both of the opponent's kings must be captured to win the game. (if you've never played this, try it. it has more strategy than original chess.) anyhow, you can "check" an opponent's king using a pinned piece if you still have both kings, since the loss of one of your pieces is not fatal. erich

whoever *can* take the other's king first is the winner.
